My main research interests lie in the area of
memory-hierarchy efficient algorithms, especially I/O-efficient algorithms
for problems involving massive datasets. I have worked on massive dataset
problems in many fundamental areas, but much of my work has been on
I/O-efficient algorithms and data structures for problems with practical
applications in geographical information systems and spatial databases. I
have investigated the practical merits of theoretically developed
I/O-efficient algorithms in projects such as TPIE, TerraFlow, Stream and TerraStream.

I am co-founder of the company Scalable Algorithmics (SCALGO), established to commercialize I/O-efficient
technology for processing of massive terrain data.
